  • the shape of the cross section of the filter portion 20C is not particularly limited, and may be, for example, circular, elliptical, polygonal, or the like.
  • destructible capsules containing perfume, perfume beads, and perfume may be directly added to the filter portion 20C.
  • the filter part 20C may have a center hole part as the first segment 25.
  • the center hole portion is composed of a first filling layer 25a having one or more hollow portions and an inner plug wrapper (inner wrapping paper) 25b covering the filling layer.
  • the center hole portion has a function of increasing the strength of the mouthpiece portion.
  • the center hole portion does not have the inner plug wrapper 25b, and the shape may be maintained by thermoforming.

  • the second segment 26 is composed of a second filling layer 26a and an inner plug wrapper (inner wrapping paper) 26b covering the filling layer.
  • the second filling layer 26a has an inner diameter of ⁇ 5.0 to ⁇ 1.0 mm, for example, filled with cellulose acetate fibers at a high density and hardened by adding 6 to 20% by weight of a plasticizer containing triacetin to the weight of the cellulose acetate. It can be a rod. Since the second packed layer has a high packing density of fibers, air and aerosol flow only in the hollow portion during suction, and hardly flow in the second packed layer. Since the second filling layer inside the center hole portion is a fiber filling layer, the feeling of touch from the outside during use does not make the user feel uncomfortable.
  • the first filling layer 25a and the second filling layer 26a are connected by an outer plug wrapper (outer wrapping paper) 27.
  • the outer plug wrapper 27 can be, for example, a cylinder of paper.
  • the tobacco rod portion 20A, the cooling portion 20B, and the connected first and second filling layers 25a and 26a are connected by a mouthpiece lining paper 28. As shown in FIG. These connections can be made, for example, by applying paste such as vinyl acetate paste to the inner surface of the mouthpiece lining paper 28 and winding the three members. These members may be connected in a plurality of times with a plurality of lining papers.
  • a combination of a non-combustion heating tobacco flavor inhalation article and a heating device for generating an aerosol is also called a non-combustion heating tobacco flavor inhalation system.
  • a non-combustion heating tobacco flavor inhalation system includes a non-combustion heating tobacco flavor inhalation article 20 and a heating device 10 that heats a tobacco rod portion 20A from the outside.
  • the heating device 10 includes a body 11, a heater 12, a metal tube 13, a battery unit 14, and a control unit 15.
  • the body 11 has a tubular concave portion 16, and a heater 12 and a metal tube 13 are arranged at positions corresponding to the tobacco rod portion 20A inserted therein.
  • the heater 13 can be a heater based on electric resistance, and electric power is supplied from the battery unit 14 according to an instruction from the control unit 15 for temperature control, and the heater 12 is heated. Heat emitted from the heater 12 is transmitted to the tobacco rod portion 20A through the metal pipe 13 having high thermal conductivity.
  • the heating device 10 may heat the tobacco rod portion 20A from the inside.
  • the heating temperature of the heating device 10 is not particularly limited, but is preferably 400°C or less, more preferably 150 to 400°C, and even more preferably 200 to 350°C. A heating temperature indicates the temperature of the heater of the heating device 10 .
  • Example A A paper-made tobacco sheet was prepared as the component (A).
  • the sheet contained tobacco material and 15% by weight of vegetable glycerin as an aerosol-generating substrate.
  • a saturated fatty acid shown in Table 1 was prepared as component (B) and sprayed onto the sheet.
  • Table 1 shows the amount of component (B) added per dry matter weight of the tobacco composition (total of paper-made tobacco sheet and component (B)).
  • the amount of octanoic acid added was 1.0% by mass based on the dry matter weight of the tobacco composition.
  • a non-combustion heating tobacco flavor inhalation article having the structure shown in FIG. 3 was manufactured.
  • the length of each segment was as follows. Tobacco segment: 12mm Center hole part: 8mm Paper tube: 20mm Acetate filter: 40mm Using a hollow cylindrical heater with an outer diameter of 3.2 mm and an inner diameter of 1.3 mm, the non-combustion heating tobacco flavor inhalation article was heated under the following conditions to carry out a smoking test.
  • Example A A non-combustion heating tobacco flavor inhalation article was produced in the same manner as in Example A, except that component (B) was not used.
  • Example B The following materials were prepared.
  • a non-combustion heated tobacco flavor inhalation article was manufactured and evaluated by the following procedure. 1) Tobacco lamina was pulverized with a lab mill to obtain fine tobacco powder having a raw material particle size D90 of 100 ⁇ m. 2) Granular palmitic acid and sucrose palmitate were pulverized with a lab mill to obtain a powder. 3) The softwood pulp was crushed with a lab mill. 4) These powdered materials were placed in a Ken mixer and mixed by stirring. 5) Liquid or pasty materials such as water, glycerin, licorice, liquid sugar, binder, etc. were placed in a mixer (manufactured by Primix) and mixed for 30 minutes.
  • a predetermined amount of the shredded tobacco composition was rolled up with wrapping paper into a size of ⁇ 7 ⁇ 20 mm to produce a single roll.
  • a single roll was used as a tobacco rod to obtain a non-combustion heating tobacco flavor inhalation article shown in FIG. 13)
  • the non-combustion heated tobacco flavor inhalation article was inserted into a heating device (PloomS manufactured by Japan Tobacco Inc.), heated, and subjected to smoking evaluation. Sensory evaluation was performed by well-trained panelists. Table 2 shows the evaluation results.
